PrintPropertyDictionary.SetProperty(String, PrintProperty) 方法

定義

將指定屬性的值設定為某個屬於 PrintProperty 所衍生類別的物件。Sets the value of the specified attribute to an object of a class that is derived from PrintProperty.

public:
 void SetProperty(System::String ^ attribName, System::Printing::IndexedProperties::PrintProperty ^ attribValue);
public void SetProperty (string attribName, System.Printing.IndexedProperties.PrintProperty attribValue);
member this.SetProperty : string * System.Printing.IndexedProperties.PrintProperty -> unit
Public Sub SetProperty (attribName As String, attribValue As PrintProperty)

參數

attribName
String

屬性的名稱。The name of the attribute.

attribValue
PrintProperty

屬於 PrintProperty 所衍生類型的物件。An object of a type that is derived from PrintProperty.

例外狀況

attribName 已經存在字典中,並且已經有 attribValue 值。attribName is already in the dictionary and it already has the value attribValue.

範例

下列範例將示範如何使用這個方法,從現有印表機的內容,只在位置、埠和共用狀態中安裝不同的印表機。The following example shows how to use this method to install a second printer that differs in its properties from an existing printer only in location, port, and shared status.

LocalPrintServer myLocalPrintServer = new LocalPrintServer(PrintSystemDesiredAccess.AdministrateServer);
PrintQueue sourcePrintQueue = myLocalPrintServer.DefaultPrintQueue;
PrintPropertyDictionary myPrintProperties = sourcePrintQueue.PropertiesCollection;

// Share the new printer using Remove/Add methods
PrintBooleanProperty shared = new PrintBooleanProperty("IsShared", true);
myPrintProperties.Remove("IsShared");
myPrintProperties.Add("IsShared", shared);

// Give the new printer its share name using SetProperty method
PrintStringProperty theShareName = new PrintStringProperty("ShareName", "\"Son of " + sourcePrintQueue.Name +"\"");
myPrintProperties.SetProperty("ShareName", theShareName);

// Specify the physical location of the new printer using Remove/Add methods
PrintStringProperty theLocation = new PrintStringProperty("Location", "the supply room");
myPrintProperties.Remove("Location");
myPrintProperties.Add("Location", theLocation);

// Specify the port for the new printer
String[] port = new String[] { "COM1:" };

// Install the new printer on the local print server
PrintQueue clonedPrinter = myLocalPrintServer.InstallPrintQueue("My clone of " + sourcePrintQueue.Name, "Xerox WCP 35 PS", port, "WinPrint", myPrintProperties);
myLocalPrintServer.Commit();

// Report outcome
Console.WriteLine("{0} in {1} has been installed and shared as {2}", clonedPrinter.Name, clonedPrinter.Location, clonedPrinter.ShareName);
Console.WriteLine("Press Return to continue ...");
Console.ReadLine();
Dim myLocalPrintServer As New LocalPrintServer(PrintSystemDesiredAccess.AdministrateServer)
Dim sourcePrintQueue As PrintQueue = myLocalPrintServer.DefaultPrintQueue
Dim myPrintProperties As PrintPropertyDictionary = sourcePrintQueue.PropertiesCollection

' Share the new printer using Remove/Add methods
Dim [shared] As New PrintBooleanProperty("IsShared", True)
myPrintProperties.Remove("IsShared")
myPrintProperties.Add("IsShared", [shared])

' Give the new printer its share name using SetProperty method
Dim theShareName As New PrintStringProperty("ShareName", """Son of " & sourcePrintQueue.Name & """")
myPrintProperties.SetProperty("ShareName", theShareName)

' Specify the physical location of the new printer using Remove/Add methods
Dim theLocation As New PrintStringProperty("Location", "the supply room")
myPrintProperties.Remove("Location")
myPrintProperties.Add("Location", theLocation)

' Specify the port for the new printer
Dim port() As String = { "COM1:" }


' Install the new printer on the local print server
Dim clonedPrinter As PrintQueue = myLocalPrintServer.InstallPrintQueue("My clone of " & sourcePrintQueue.Name, "Xerox WCP 35 PS", port, "WinPrint", myPrintProperties)
myLocalPrintServer.Commit()

' Report outcome
Console.WriteLine("{0} in {1} has been installed and shared as {2}", clonedPrinter.Name, clonedPrinter.Location, clonedPrinter.ShareName)
Console.WriteLine("Press Return to continue ...")
Console.ReadLine()

備註

如果字典未包含 attribName ,則 attribName 會加入並設定為 attribValue ,但前提是這與 attribName 相同 attribValue 。名字。If the dictionary does not already contain attribName, attribName will be added and set to attribValue, provided that attribName is identical to attribValue.Name. 如果這些值不相同,則這個方法不會執行任何動作。If these values are not identical, this method does nothing.
